Not that I know of. I think the two most prominent open-source models that we hear about are Whisper and Parakeet!
Parakeet does list its training data, and at least one of those is not FOSS, but some of them definitely are FOSS. I wonder if they nVidia would create a fully FOSS model by retraining on only the open data.
